Technical Specifications - NTN 4T-09067/09195

The dimensions and catalogue parameters refer to the NTN 4T-09067/09195 bearing assembly.

Important dimensional distinction: The overall bearing width T is 18.034 mm, while the inner ring width B is 19.050 mm. These dimensions are not interchangeable.

For tapered roller bearings, the overall assembly width must be distinguished from the individual widths of the inner and outer rings.

What Does NTN 4T-09067/09195 Mean?

The complete designation identifies the bearing manufacturer, design version and the two components forming the tapered roller bearing assembly.

4T - NTN Bearing Design

The prefix 4T identifies an NTN tapered roller bearing design associated with the manufacturer's heat treatment technology.

NTN uses this designation for bearing constructions incorporating specific material treatment characteristics.

The prefix is technically significant and should be preserved when identifying or ordering the bearing.

It should not be omitted or interpreted as a universal suffix used by all bearing manufacturers.

09067 - Cone Assembly

The designation 09067 identifies the inner ring assembly, commonly referred to as the cone.

This assembly includes:

• Inner ring with tapered raceway.

• Tapered rolling elements.

• Roller cage.

The cone forms the rotating or shaft-mounted component of the bearing arrangement, depending on the machine design.

09195 - Outer Ring or Cup

The designation 09195 identifies the matching outer ring, commonly referred to as the cup.

The cup contains the outer tapered raceway and is normally mounted in the bearing housing.

The cone and cup must be selected as a compatible combination.

Meaning of the Slash in 09067/09195

The slash separates the cone and cup designations.

The complete bearing designation identifies the combination of these two components.

The original slash must be retained when specifying the product:

4T-09067/09195

Replacing the slash or changing the part numbers may prevent accurate product identification.

Construction and Operating Principle

NTN 4T-09067/09195 is a separable single row tapered roller bearing.

Its construction consists of a cone assembly and a matching outer ring.

The tapered rollers operate between the conical inner and outer raceways.

This geometry enables the bearing to accommodate radial loads and axial loads acting in one direction.

Tapered Rolling Elements

Unlike cylindrical roller bearings, tapered roller bearings have conical rolling elements and raceways.

Their geometry allows the rolling contacts to transmit combined loads.

The bearing is therefore suitable for arrangements where radial loading is accompanied by axial forces.

Separable Construction

The cone assembly and cup can be separated.

This design facilitates the installation of the inner and outer bearing components in their respective mounting positions.

However, the two components must form the correct bearing combination.

A cup or cone with a different reference number should not be assumed to be interchangeable.

Pressed Steel Cage

NTN 4T-09067/09195 uses a pressed steel cage.

The cage maintains the circumferential spacing of the tapered rollers and helps guide their movement during operation.

Open Bearing Design

The bearing is supplied in an open construction without integrated contact seals or metal shields.

The complete machine arrangement must provide suitable lubrication and protection against external contamination.

Radial and Axial Load Capacity

The tapered roller geometry allows NTN 4T-09067/09195 to accommodate combined loading.

Basic Dynamic Load Rating C

The basic dynamic load rating is used in calculating nominal bearing fatigue life.

It is not the maximum permissible operating load under every condition.

Bearing life depends on equivalent loading, rotational speed, lubrication, contamination and operating conditions.

Basic Static Load Rating C0

The basic static load rating relates to a defined criterion for permanent deformation at the rolling contacts.

Static safety requirements must be evaluated according to the application.

Fatigue Load Limit Cu

The catalogue fatigue load limit is a parameter used in bearing life assessment.

It must not be interpreted as an unconditional permissible load or a substitute for dynamic and static load calculations.

Operating Speeds and Lubrication

The NTN catalogue specifies different limiting speeds depending on the lubrication method.

These values are catalogue limiting speeds, not guaranteed operating speeds for every installation.

Actual permissible speed depends on the bearing arrangement, load, lubricant, temperature, preload and operating conditions.

Grease Lubrication

Grease lubrication may be suitable where the operating conditions and maintenance arrangements permit.

The grease must be selected according to speed, temperature, loading and environmental conditions.

Oil Lubrication

Oil lubrication may be used in systems requiring continuous lubricant supply or enhanced heat removal.

The lubrication method and oil viscosity must be selected according to the application.

The bearing designation itself does not specify a particular grease or oil grade.

NTN 4T-09067/09195 vs Other Tapered Roller Bearing Versions

The complete NTN designation identifies a specific cone and cup combination.

Bearings with similar dimensions or related reference numbers may differ in:

• Overall width.

• Cone width.

• Cup width.

• Internal geometry.

• Contact angle.

• Load ratings.

• Cage construction.

• Dimensional tolerances.

Why Overall Width Matters

For NTN 4T-09067/09195:

• Bore diameter d: 19.050 mm.

• Outside diameter D: 49.225 mm.

• Overall width T: 18.034 mm.

• Cone width B: 19.050 mm.

• Cup width C: 14.288 mm.

The dimensions 19.050x49.225x19.050 mm describe the bore diameter, outside diameter and cone width, not the complete bearing envelope.

The correct overall dimensions are 19.050x49.225x18.034 mm.

A replacement bearing must be evaluated using the correct overall width and the complete component designation.

Alternative Designations and Reference Numbers

The bearing may be identified using the following natural reference formats:

• NTN 4T-09067/09195

• 4T-09067/09195 NTN

• NTN 09067/09195

Can a Bearing from Another Manufacturer Be Used?

A bearing from another manufacturer with matching cone and cup references may be considered as a potential alternative.

However, complete interchangeability must be confirmed by comparing dimensional tolerances, internal geometry, load ratings and application requirements.

Identical dimensions alone do not guarantee equivalent operating performance.

Can the Cone and Cup Be Replaced Separately?

The cone and cup are separable components, but their compatibility must be maintained.

When replacing an individual component, verify that the remaining component is suitable, undamaged and compatible with the replacement.

For maintenance applications, replacing the complete matched bearing assembly may be preferable where wear or damage is present.

Applications of NTN 4T-09067/09195

Single row tapered roller bearings are used in mechanical arrangements requiring combined radial and axial load capacity.

Typical application categories for this bearing type include:

• Rotating shaft supports.

• Equipment requiring adjustable axial clearance or preload.

These are general applications of single row tapered roller bearings, not confirmed OEM applications for NTN 4T-09067/09195.

The bearing's suitability for a particular machine must be established using the original equipment specification or an engineering assessment.

Axial Load Direction

A single row tapered roller bearing accommodates axial load in one direction.

When axial loads act in both directions, an appropriately designed opposed bearing arrangement is generally required.

This is a fundamental consideration when selecting a tapered roller bearing for a shaft assembly.

Installation and Maintenance

Correct installation is essential for tapered roller bearing performance.

Before mounting:

• Inspect the shaft and housing surfaces.

• Remove contamination from mounting areas.

• Verify the required shaft and housing fits.

• Apply mounting forces to the ring being installed.

• Avoid transmitting mounting forces through the rolling elements.

• Use a suitable lubricant.

• Adjust axial clearance or preload according to the equipment specification.

Bearing Clearance and Preload

Unlike many deep groove ball bearings, tapered roller bearings are commonly installed in arrangements where operating clearance or preload is established during assembly.

Incorrect adjustment may cause excessive friction, overheating, vibration or premature damage.

The correct setting depends on the bearing arrangement and the manufacturer's equipment requirements.

Storage

Store NTN 4T-09067/09195 in its original protective packaging in a clean, dry environment.

Protect the bearing from moisture, dust, corrosion and mechanical impact.
